Sound that follows the picture.

Paraplex scores a piece to its own cuts, puts a sound on every motion, and adds a voice with captions on each word. Everything is mixed on the same timeline as the animation, and the export carries the whole mix.

Score a pieceHow scoring works

The film below was made and scored in Paraplex: a template, one sound design pass, and a score written to its three parts. Turn the sound on to hear it.

Loupe: Make, a 20-second launch film made in Paraplex from a template, given one sound design pass and a score of piano and strings written to its three parts

From silent to mixed in four steps.

Each step lands on the timeline as clips you can move, trim and mix. Nothing is lined up by hand in another app.

Step 1

Sound design.

One pass puts a sound from the built-in library on every motion: a whoosh on a slide, a click on a tap, a riser before the logo.

Step 2

A score.

Paraplex reads the cuts, the logo landing and the voice, splits the piece into parts there, and writes music to each.

Step 3

A voice.

Pick a voice from the shelf and type the script, or record your own. Captions are timed to each word.

Step 4

The mix.

Faders, pan, effects and ducking per track, and a loudness target for where the video goes.

Music written to the picture, not laid under it.

Score this piece splits the piece at its cuts, its hits and the logo landing, and writes what the music does in each part: quiet under the voice, building to the reveal, a hit as the logo lands. You see the plan and can edit it before anything is made. Change one part's words and Rewrite only this writes that part again, crossfaded in, leaving the rest exactly as it was.

A sound on every motion.

More than 60 sounds made for motion: whooshes, pops, clicks, risers, impacts, typing and ticks, each heard in place with the scene before it is added. Right-click a layer that moves and Paraplex suggests the sound for each of its motions, or describe one and make up to four takes side by side.

A voice from the shelf, or your own.

Ten voices, each with a sample to hear before you choose. Or record your own: a count of three, then a prompter that lights each word as you read it. Clean up takes out the room and the noise. Every voice gets captions timed to its words, and the music ducks under it.

Mixed on one timeline, exported in one file.

Each bus has a fader, pan, meters and effects: EQ, compressor, reverb, delay, filter. Draw volume over time, duck the music under the voice, and set the loudness for streaming, podcasts or broadcast. The video exports with the whole mix, or export the sound alone and its stems.

Questions about sound in Paraplex

Is the music made for my video, or picked from a library?

Made for it. Score this piece reads your piece's cuts, hits and logo landing, splits it into parts there, and writes music to those lengths. The sound effects are a built-in library, free to use.

Can I change one part of a score?

Yes. Edit that part's words and choose Rewrite only this. Only that part is written again and crossfaded in; the rest stays as it was.

Can I use my own music and voice?

Yes. Import audio files, or record your voice in the Voiceover window. A recorded or imported voice gets Voice polish and can have its words found for captions.

Does the export include the sound?

Yes. MP4 and WebM carry the full mix at the loudness you choose. You can also export the sound alone, or each bus as a stem.

Can I use my own ElevenLabs account?

Yes. Add your key and voiceovers, scores and sounds run on it, with your own cloned voices on the shelf's list.

Coming soon: post straight to your accounts.

Not available yet. Two things are on the way for marketing teams. The first is posting finished pieces straight to your linked social accounts.

The second is a long-form YouTube workflow for 3D documentaries, educational videos and tutorials: an outline and research, a voiceover, B-roll and generated 3D scenes, edits timed to the narration with music, sound and titles, landscape and vertical renders for each platform, and titles, descriptions and hashtags written for each post. Both will be listed here when they ship.

“Every client has a brand.”

A design system per client.

Keep each client's colors, fonts, text styles, materials, scene looks and motion as its own design system in your Library, and apply it to any scene in one step. A client's kit exports as one file to share with a teammate.

“The revisions never end.”

A link for review, a step to undo.

Copy a shareable link that publishes the piece as a web page, then refresh it after each round while the address stays the same. Notes on the canvas never export, undo has no limit, and each project keeps a History of recent saves to restore.

“The volume keeps growing.”

Templates, including your own.

Start from 70+ editable templates that each say what to swap in, or save any scene as a template of your own. Data variants make one version per spreadsheet row, and on Pro, Export all variants renders them in one job.

“Every channel wants its own size.”

One scene, every format.

Add 16:9, 9:16, 1:1, 4:5 or 4:3 as artboards beside the frame, each reframed for its shape, with safe zones for TikTok, Reels, Shorts and the Instagram feed. On Pro, one export renders every enabled format.

Your own code, running live inside it.

Code layers bring HTML, CSS, JavaScript or React into a scene, flat over the frame or as a card in 3D. In an embed they keep running and respond to the pointer, so a live counter or a slice of your product's UI can sit inside the 3D scene on your site.

Camera

A camera they can move.

Let viewers Orbit, Look around like a panorama, Walk with W A S D or two fingers on a phone, or keep the camera Fixed.

States

States, not just a loop.

Idle loops, presses that play once and hold, and held poses, switched by clicks, the pointer, a delay or your page.

Keyboard

Reachable without a mouse.

Every interactive layer gets a keyboard-focusable stand-in, so visitors can reach it with Tab and press it with Enter.

Reduced motion

Calm for anyone who asks.

Visitors who ask their device for less motion see the first frame held instead of the animation.

Can I automate narrated videos, for example for a YouTube channel?

Yes, for motion design videos. The assistant can build a narrated, captioned piece from a description and wait for you to apply it. An AI agent such as Claude Code, connected through the Paraplex MCP server, can open a template, add the voiceover, check the frames and export the video from your terminal. One scene reframes for 16:9, 9:16, 1:1 and 4:5, so a YouTube video and its Short come from the same build.

Is Paraplex an automated video editor for camera footage?

Not mainly. Paraplex makes motion design videos: 3D scenes, type, charts and product demos, with their voice, captions and music. Video clips can sit on the timeline as layers and be trimmed, but their own sound isn't played, so for cutting talking-head or camera footage a video editor is the better tool. Many teams use both: cut the footage there, and make the narrated motion pieces in Paraplex.

Does the voiceover come through in the export?

Yes. Every audio track, the voiceover included, is mixed into MP4 (AAC) and WebM (Opus) exports, for pieces up to an hour, and transparent WebM keeps its sound. GIFs and PNG sequences have no sound.

Is AI voiceover free?

The voiceover tool is on every plan, Free included. Each voiceover uses Paraplex AI credits from your account. Add your own ElevenLabs key and voiceovers run on your ElevenLabs account instead, with no Paraplex credits used. Exports are free up to 1080p with no watermark; Pro adds 4K.
